How to Use

Jack's Hydroponic is a water-soluble fertilizer designed to be mixed with water for the most accurate and effective nutrient delivery to the plant.

For Best Results

Jack's Fertilizers are made with 100% soluble raw materials that will form a true solution.

For best results, use warm or hot water (180 F) to dissolve product. Some raw materials are slower to dissolve than others. Most fertilizer compounds dissolve in an endothermic reaction which means they absorb heat from their surroundings during the process. In strong conentrations or stock solutions (1-3+ lbs per gallon) using cold water in a cold environment will drastically slow the dissolving process ( up to 24 hours to form a true solution). In all conditions, agitation will help speed up the dissolving process by exposing more particle surface area to the water.
